MCSCOM is giving away 68 (at the time of posting) £50 discounts on its Dell Dimension refurbished PCs. These, unlike other refurbished computers there, come with the operating system and an onsite 3 year Dell warranty. The one that caught my eye is the cheapest Dual Core computer I've ever come across. It is a Dell Dimension 5150. It might only be a Pentium D 805 system but it is still a capable workhorse

Note that there are also other systems should this one be out of stock. Also I am not affiliated with Mark from MCSCOM ;-) I just happen to receive their emails. http://www.mcscom.co.uk/section.php?xSec=48
